Numerical study on an integrated system of a wave energy converter and a breakwater

The study focuses on the characteristics of an integrated system that consists of a FOWC and a breakwater. A numerical wave tank (NWT) is designed based on Reynolds Averaged Navier-Stokes equation and overset mesh. A mesh study is conducted to determine the most accurate configuration whereas validation to numerical and experimental data is conducted to ensure the validity of the results of present study. A FOWC with and without breakwater was used in this study to compare their characteristics. Results show that the addition of breakwater enhanced the wave energy extraction at lower angular frequency. This finding may indicate favorable conditions that contribute to the higher energy extraction efficiency of the integrated system.
